Answer:

ASA

Step-by-step explanation:

Triangle ABD is congruent to triangle BDC by ASA because angle B in ABD  is 30 degrees. Then they give you BD which equals BD by the reflexive property. And finally angle D in ABD is also 30 degrees. In triangle BCD, angle B is 30 degrees, BD = BD, and angle D in BCD is 30 degress. So we have an angle (B), side (BD), and another angle (D)

The profit of a company receives is given by the expression 0.15(855p - 315) where p is the number of problems sold. Rewrite thi
Goryan [66]

The profit for 25 products sold and 150 products sold are 3159 and 19190.25 respectively.

<u><em>Explanation</em></u>

The profit of a company receives is given by the expression:  0.15(855p - 315)

Simplifying this expression using distributive property, we will get .....

0.15(855p - 315) \\ \\ = (0.15*855p)-(0.15*315)\\ \\ =128.25p-47.25

So, the simplified expression for profit will be:  128.25p-47.25

As p represents the number of products sold, so for finding the profit for 25 products sold and 150 products sold, <u>we need plug p=25 and p=150 separately into the above expression</u>.  

For p=25,  Profit =128.25(25)-47.25 = 3206.25-47.25= 3159

For p=150, Profit =128.25(150)-47.25 = 19237.50-47.25= 19190.25

What is the perimeter of ΔABC?
Serggg [28]

Answer:

Choice D:  Perimeter = 5 + \sqrt{65} +  \sqrt{34}  units

Step-by-step explanation:

point B(9, 2)  , point C(4, 5),  point A (1,1)

Perimeter = D( A, C)  + D (A, B)  + D (B, C)

where D (A, C) =  distance between A and C

so...

D(A, C) = root ( (4 - 1)^2 + (5 - 1)^2) = 5   from a 3-4-5 right triangle.

D(A, B) = root( (9- 1)^2 + (2 -1)^2) = root( 64 + 1) = root(65)

D(B, C) = root( (9 -4)^2 + (2 -5)^2) = root (25 + 9) = root(34)

Perimeter = 5 + root(65) + root(34)

Perimeter = 5 + \sqrt{65} +  \sqrt{34}  units
